실험 절차

To the DMF solution (20 ml) of 3-Amino-3-(3-ethoxy-4-methoxy-phenyl)-propionitrile (1.55 g, 7 mmol) was added Et3N (1.6 ml, 12 mmol) followed by 2-bromomethyl-3-chloro-6-(cyclopropanecarbonyl-amino)-benzoic acid methyl ester (2.42 g, 7 mmol). The mixture was heated at 90° C. for 12 hrs then cooled to room temperature. The mixture was extracted with EtOAc (50 ml) and water (50 ml). The organic layer was washed with water (50 ml) and brine (50 ml), dried over Na2SO4 and concentrated in vacuo. The resulted oil was purified by silica gel chromatography to give cyclopropanecarboxylic acid {7-chloro-2-[2-cyano-1-(3-ethoxy-4-methoxy-phenyl)-ethyl]-3-oxo-2,3-dihydro-1H-isoindol-4-yl}-amide as white solid (2.4 g, 80%): mp 200-202° C.; 1H NMR (CDCl3)δ 0.90-0.94 (m, 2H, c-CH2), 1.09-1.14 (m, 2H, c-CH2), 1.45 (t, J=7.0 Hz, 3H, CH3), 1.64-1.70(m, 1H, c-CH), 3.12-3.32(m, 2H; CH2CN), 3.89(s, 3H), 3.99-4.12 (m, 3H, OCH2CH3+CHHN), 4.37 (d, J=18 Hz, 1H.
